Could you please post the thread title or a link to that thread?
Sure Bob, I made a handful of posts regarding the Edison (or nickle/iron) battery which has many positive attributes but like everything else it is not perfect. http://www.freerepublic.com/focus/f-bloggers/2848984/posts
Given its longevity and low toxicity it would seem a great starting point for at bare minimum an interim method until something better came along.
If other issues with electric cars and their power source are addressed, removing a larger battery and replacing it with a smaller one would not be a game changer. Right now we are experiencing politician induced technological grid lock.
